Influence of Habitat on Ceratitis capitata Response to Trimedlure Traps
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), occurs in diverse habitats ranging from semi-tropical to temperate. C. capitata is noted for its ability to adapt to a variety of diverse habitats (Nishida et al., 1985). Some of the key factors influencing distribution and abundance of C. capitata include the habitat, the climate, and the fruiting phenology of host plants. In the tropics, temperature is almost always favorable and food and shelter available (Harris and Lee, 1987). Under these conditions, this fly is not stressed from lack of essential resources or by being required to live under low temperature conditions. In south America in desert areas of Chile and Peru, C. capitata must adapt to climatic stress from drought, low temperatures, and lack of food and shelter. We were concerned about how the fly adapts to the environment under desert conditions. We hypothesized that the insect may show differences in behavior that could be easily measured to show adaptation similarities and differences. Therefore, parallel studies were conducted in Chile and Hawaii to assess the response by gender of C. capitata to the male attractant trimedlure.
